Hi i watched your instruction video on the moisture sensor, and now i have tried my own senor and i have a couple of questions.
My reads dry 4.34V and wet 3.55V. Is this "normal"?
And my sensor doesn't respons as quick as in your video. It takes a longer time and responses real slow.
Is this normal? I think it should not matter.
Really like the hat and the software.
Kind regards
Thank you for your answer, as some as i have a real situation i will post some charts and photo's
It may be "normal" depending on the sensor. I have purchased several capacitive sensor v1.2 and they are not all the same, probably it depends on the manufacturer.
This is one of the main reason why we require calibration.
The fact that is not quick is quite interesting, seems they used a bigger capacitor in that sensor. Anyway the soil moisture is not a fast changing measure so it is fine. Probably this will make the reading more stable.
If you use the sensor in real scenario, It would be nice if you can post a screenshot with the Chart.
